JOINT PRESS RELEASE

MAGNA AND TESMA ANNOUNCE AGREEMENT
FOR PRIVATIZATION OF TESMA

December 23, 2004, Aurora, Ontario, Canada — Magna International Inc. (TSX: MG.SV.A, MG.MV.B, NYSE: MGA) ("Magna") and Tesma International Inc. (TSX: TSM.SV.A; NASDAQ: TSMA) ("Tesma") today jointly announced that they have entered into a definitive arrangement agreement by which Magna would acquire all the outstanding Class A Subordinate Voting Shares of Tesma not owned by Magna, to be carried out by way of a court-approved plan of arrangement under Ontario law. This proposal by Magna to privatize Tesma was previously announced on October 25, 2004.

Under the terms of the arrangement agreement, shareholders of Tesma will receive 0.44 of a Class A Subordinate Voting Share of Magna for each Class A Subordinate Voting Share of Tesma or, at the election of any shareholder of Tesma, cash based on the volume-weighted average trading price of Magna's Class A Subordinate Voting Shares on the Toronto Stock Exchange over the five trading days ending on the last trading day immediately preceding the effective date of the plan of arrangement. The aggregate cash payable to all electing Tesma shareholders will be capped at Cdn. $350 million. If shareholders of Tesma elect to receive cash in excess of Cdn. $350 million in the aggregate, the total cash available will be prorated among those shareholders electing to receive cash and the balance of their consideration will be satisfied in Magna Class A Subordinate Voting Shares.

The Tesma Board of Directors approved the arrangement agreement following the report and favourable recommendation of its Special Committee of independent directors established to review and consider the arrangement. In doing so, the Tesma Board determined that the arrangement is in the best interests of Tesma and its shareholders, and authorized the submission of the arrangement to holders of Tesma Class A Subordinate Voting Shares for their approval as required under applicable law. UBS Securities Canada Inc. ("UBS"), the independent valuator and financial adviser to the Special Committee, concluded that, as at the close of markets on December 22, 2004, the consideration being offered to holders of Tesma Class A Subordinate Voting Shares under the arrangement is fair, from a financial point of view, to the minority holders of Tesma Class A Subordinate Voting Shares. A copy of the UBS valuation and fairness opinion, the factors considered by the Special Committee and Tesma's Board and other relevant background information will be included in the management information circular/proxy statement that will be sent to holders of Tesma Class A Subordinate Voting Shares in connection with the special meeting to be called to consider the arrangement.

Tesma has set a record date of January 1, 2005 for shareholders entitled to receive notice of the special meeting. Subject to court approval, Tesma expects to hold the special meeting on February 1, 2005 in Toronto and expects that the arrangement, if approved, will become effective on February 6, 2005. The arrangement will require approval by two-thirds of the votes cast by holders of Tesma Class A Subordinate Voting Shares and Tesma Class B Shares, with each class voting separately. The arrangement also requires the approval of a simple majority of the votes cast by the minority holders of Tesma Class A Subordinate Voting Shares. Magna, and parties related to Magna, including its directors and senior officers, may not vote their Tesma Class A Subordinate Voting Shares for the purposes of this "majority of the minority" approval requirement.

The Tesma Board of Directors also today declared a dividend of Cdn. $0.24 per Tesma Class A Subordinate Voting Share and Tesma Class B Share, payable on or after February 15, 2005 to shareholders of record on February 3, 2005.
